Actually, the ones without the markings were defective.
I hate to see you bang your head on a defective rifle...... If you want to send it to me, I can part it out for you.

Do you really think we want laws to be observed? We want them broken. There's no way to rule innocent men. The only power any government has is the power to crack down on criminals. When there aren't enough criminals, one makes them. One declares so many things to be crimes that it becomes impossible for men to live without breaking laws. Who wants law-abiding citizens? Pass the kind of laws that can’t be observed, enforced, or objectively interpreted - and you create a nation of law-breakers.

Thanks for all the info, I am working on upgrading my XCR-L(its approx a 2009). When I bought it, it already had the newer gas system (looks like a gen 2). After reading the posts here it says it may cause an over gassed gun. When I adjust the gas setting the brass ejects the same distance, about 10-12 ft, on all settings but S. Is this a symptom of an over gassed gun.
